Abstract
Purpose
Although studies have investigated reasons for software as a service (SaaS) adoption, it is unclear how firm-level SaaS use impacts future SaaS intentions. The purpose of this paper is to propose a theoretical model that integrates the technology-organization-environment framework, institutional theory, diffusion-of-innovation theory and the opportunity-risk framework to analyze the drivers of SaaS use and its continuance intention.
Design/methodology/approach
The authors evaluated the direct, moderating and mediating effects of determinants on SaaS continuance intentions using structural equation modeling and data from 301 firms.
Findings
Results found that top management support and normative pressures influenced SaaS use. Cost saving and security concerns were direct predictors of perceived opportunities and perceived risks, respectively. Perceived opportunities and risks and actual SaaS use influenced SaaS continuance. Interestingly, perceived opportunities were found to be a negative moderator on the relationship between SaaS use and SaaS continuance.
Originality/value
The results reveal insightful and controversial findings for SaaS research.

Abstract
Purpose
This paper aims to explain and demonstrate how the Repertory Grid Technique (RGT) and Honey’s Content Analysis (HCA) can make new contributions to the field of Operations and Supply Chain Management (OSCM). The proposition involves integrating these complementary analyses to fortify the rigor of qualitative research and establish robust data analysis protocols to identify the main attributes of interviewees regarding a phenomenon while understanding in their perspective how these attributes impact the desired analysis outcome.
Design/methodology/approach
This study uses examples with rich empirical data from 40 interviewees across two organizations. The examples use a protocol that allows the grouping of meanings from different knowledgeable individuals and capturing relevant constructs related to an outcome.
Findings
The combination of RGT and HCA permits researchers to effectively identify and analyze the constructs individuals and groups utilize to comprehend the subject matter under investigation. Consequently, these techniques present a structured means to conduct grounded theory investigations and interpretive research, thereby enabling the iterative development of the preliminary conceptual models necessary for OSCM field advancement.
Originality/value
We present two examples in which the protocol is applied to the field of OSCM. These examples illustrate that the techniques provide valuable opportunities for OSCM research, particularly for addressing the limitations related to sample size. Ultimately, RGT and HCA complement quantitative methodologies by uncovering nuanced variations and micro-foundations within firm- and network-level phenomena, offering insights essential for advancing our understanding of OSCM dynamics in specific contexts.

Abstract
Purpose
The purpose of this paper is to determine the differences in the values and behaviours of employees and entrepreneurs and to develop guidelines for employers to foster entrepreneurial thinking in their organisations.
Design/methodology/approach
To determine individual behaviours, the authors used the career adaptability scale developed by Savickas and Porfelli (2012), complemented with the statements regarding relationships in the workplace and reward, designed by Gattiker and Larwood (1986). The individual values were evaluated by Schwartz’s individual value framework. The career success of individuals was defined by income level and job satisfaction. Data from a sample of 473 respondents were analysed using structural equation modelling.
Findings
This paper reveals that there are differences in the behaviours and the values of employees and entrepreneurs. Employees are more concerned with relationships at the workplace, rewards and confidence, whereas entrepreneurs focus solely on relationships. Self-direction value has a direct positive impact. Universalism, conformism, achievement, stimulation and safety have indirect positive effects on career success for employees. There is no specific individual value driving career success for entrepreneurs.
Originality/value
This paper follows the recent trends in organisational culture development whereby organisations seek to incorporate the entrepreneurial mindset at all levels of the organisation. Until now, there has been scarce empirical evidence on the differences between entrepreneurial and employee values. This research provides evidence that the value gap between these two distinct groups is considerable enough to question the ability of the average employee to adopt the entrepreneurial behaviour required by modern organisations.

This paper aims to identify the scale efficiency of dry ports in Brazil and its main technological drivers.
Abstract
Purpose
This paper aims to identify the scale efficiency of dry ports in Brazil and its main technological drivers.
Design/methodology/approach
This paper uses the Data Envelopment Analysis (DEA) model in two stages. The first stage of the DEA was used to measure the efficiency of the dry ports. In the second stage, the Bootstrap Truncated Regression (BTR) was applied to explore the relationship between efficiency and the factors analyzed. The inputs, outputs and contextual variables for this analysis were extracted from the secondary database provided by Revista Tecnologística.
Findings
In the first analysis stage, a high level of idleness was verified in the operations. The contextual variables in the second stage were significant: Certification, Warehouse Management System (WMS), barcode and Radio Frequency Identification (RFID). Results corroborate the positive impact of Information Technology (IT) coordination processes on logistics performance.
Practical implications
Results show that dry ports operate below their technical and operational capacity and that the sector's lack of regulation in Brazil can facilitate and encourage the use of ports and marine terminals by importers and exporters.
Originality/value
Application of two-stage DEA measures efficiency as a sectoral benchmarking tool.

Abstract
Purpose
This study aims to demonstrate a rigorous approach to applying the Repertory Grid Technique (RGT) and Honey’s Content Analysis (HCA) to obtain and process qualitative data through structured interviews.
Design/methodology/approach
An illustrative case study using the OpenRepGrid package from the open-source software R facilitates a deeper understanding of these techniques. The study subjects were employees of a corporate charter company.
Findings
The RGT enables the identification of key attributes as perceived by interviewees regarding the phenomenon, whereas HCA clarifies how these attributes impact the desired analysis outcome. The presented case study identified constructs related to the client–supplier relationship and their impact on service performance from the provider’s perspective.
Research limitations/implications
This study illustrates the use of qualitative methods based on an interpretative naturalistic approach to rigorously and systematically capture interviewees’ perspectives.
Practical implications
The combination of RGT and HCA can be a valuable tool for management studies by allowing controlled researcher interference in empirical investigations. In addition, the data-driven selection of constructs by interviewees can lead to the emergence of novel theories.
Social implications
Using diverse methodologies enables researchers to address complex managerial challenges that often surpass the capabilities of conventional analysis methods.
Originality/value
The proposed methodology offers a robust understanding of phenomena from the interviewees’ perspectives. Consequently, this study highlights the potential of these techniques for theoretical and empirical research in the field of administration.

Abstract
Purpose
The mine sequencing problem is NP-hard. Therefore, simplifying it is necessary. One way to do this is to employ clusters as input instead of individual blocks. The mining cut clustering problem has been little addressed in the literature, and the solutions used are almost always heuristic. We solve the mining cut clustering problem, which is NP-hard, through single- and multi-objective optimization, finding results that are local optima in acceptable computational time.
Design/methodology/approach
We first elaborate an ILP-based model to address the mining cut clustering problem. We employ a mono-objective approach and two multi-objective approaches, solving all these models by constraint programming. To choose the best solutions generated by multi-objective approaches, we employ two multi-criteria decision analysis approaches, considering different weight configurations. We developed a case study using real data.
Findings
We verified that the approaches based on multi-objective optimization performed better than the mono-objective approach for the economic return criterion. The weighted-sum multi-objective approach presented the best results considering all objective functions used. Once viable solutions were obtained through multi-objective optimization, multi-criteria decision analysis approaches almost always selected the same solution. We obtained solutions that are local optima in acceptable computational time.
Research limitations/implications
This study solves an instance with 80 blocks. Consequently, it is aimed at short-term mine planning. The methodology has not yet been evaluated in large instances related to medium- and long-term mine planning.
Originality/value
This is the first time that multi-objective optimization has been employed to solve the mining cut custering problem. Even other problems related to mine planning were, at most, solved by goal programming, so that multi-objective optimization is a knowledge that is not widespread among mining researchers. The results are consistent, and the study achieves the objective of finding quality solutions to an NP-hard problem in an acceptable computational time.

Abstract
Purpose
The purpose of the paper is to review issues and concepts related to the use of knowledge in business for the purpose of generating profit, and show their application in relation to the author's own company, Ricardo. As far as possible, both the conditions common to other knowledge companies, and those unique to Ricardo, are identified, with a view to furthering the management of knowledge by others.
Design/methodology/approach
The paper approaches the topic of knowledge management from a case‐study angle, with a view to identifying the knowledge inputs into the company's work, its processing of those inputs, and the generation of outputs in the form of profitable knowledge products and services.
Findings
The paper finds that knowledge is presented as a differentiated concept with various levels and functions. Following a description of how the various types of knowledge are used by the author's company, some of the lessons to be learned are listed.
Practical implications
The paper offers, both explicitly and by implication, some useful guidelines for KM practitioners.
Originality/value
The paper reveals how far theoretical concepts, such as tacit and explicit knowledge, knowledge bases and knowledge or learning communities, are reflected in the real world situation of Ricardo.

Abstract
We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.
